What's the History of Toothpaste?

Lauren Vogelbaum Here without teeth, life is tough. Sure we have all sorts of fancy dentistry tricks these days, but nothing tops the Choppers were born with. In fact, when rocker Patti Smith gave the commencement address at the Pratt Institute in New York, she gave those graduating seniors some incredibly sound advice. She said, now that I'm here, my greatest urge is to speak to you of dental care.

My generation had a rough go dentally. Our dentists were the Army dentists who came back from World War Two and believed that the dental office was a battle ground. You have a better chance at dental health, and it may be true that our big dental procedures are considerably better than they were in the middle of the last century. But it's the maintenance that Smith was probably talking about.

We've got to scrub our teeth each and every day, or else bacteria will calcify into tartar, which is where the tooth troubles really begin. Keeping all your teeth in your head and avoiding life threatening infection has always required constant vigilance, which is where toothpaste comes in. Now, nobody knows who invented the toothbrush. Most ancient civilizations seem to have had some variation of a frayed choo stick that they used to keep their teeth clean. But don't teeth

also need some sort of well cleaning agent. Is that minty plaster like goo that we smear on our modern chewing sticks just capitalist snake oil? Not of his story has anything to say about it. Toothpaste might actually predate

the tooth brush. While there's evidence that ancient Egyptians were using toothbrushes as far back as three thousand, five hundred b CE, recipes for tooth powder have been found the date back to five thousand BC, the earliest Egyptian tooth powder recipe contained plenty of abrasives to scrape off all the sticky residue. The ashes of burnt eggshells and oxen

hoofs mixed with pumice seemed to be popular. By the fourth century, Egyptians had fancied up their tooth powder with abrasives like rock salt and flavorings like mint and peppercorns. They even added dried iris flower, perhaps because it was associated with purification. Good thing are tooth enamel is harder than bone or even iron or steel. If it wasn't those Egyptians would have brushed their teeth right down to nubs.

But when this recipe was revealed in two thousand three at a dental conference in Vienna, Austrian dentist Heinz Newman told the Telegraph that he tried it and it wasn't half bad. He said, I found that it was not unpleasant. It was painful on my gums and made them bleed as well, but that's not a bad thing, and afterwards my mouth felt fresh and clean. I believe that this recipe would have been a big improvement on some of

the soap toothpastes used much later around the world. Different cultures continued mixing crushed abrasives like oyster shell or bone, and nice tasting herbs like mint and jin sing together to clean teeth and keep hallatosis that's bad breath at bay. But as with literally everything else, the Middle Ages didn't really do much for toothpaste technology. During this time, Europeans settled on a mixture of honey, salt, and drye flour, which they supplemented by giving their teeth a good scrubbing

with the bark of certain trees. It wasn't until the nineteenth century that the toothpaste biz as we know it really started heating up. Recipes for tooth powders and pastes that included abrasives like charcoal, chalk, and burned bread crumbs, as well as incense like dragon's blood were popular in England until eighteen fifty, when Coalgate introduced its first krem dentifrie,

which came in a jar. Mass production of this product started in the eighteen seventies, and twenty years later they introduced the collapsible tube, and from then on toothpaste was a thing. Before World War Two, most toothpastes on the market were sold in a lead tube. They also contained soap, which was unnecessary and in some cases even counterproductive, but we humans seem to have a hang up about wanting

our cleansers to foam. Toothpastes today still tend to contain soap, namely sodium laurel sulfate, because it's not clean unless it's foamy, but soap also helped maintain an even creamy texture. We can also get this smooth texture with humicants like sorbitol glycerin and propylene glycol, which have the added bonus of

being a little bit sweet. Fluoride was first added toothpaste in nineteen fourteen, but it wasn't until the nineteen sixties that it was proven to fight cavities, and modern toothpaste no longer uses chalk as an abrasive. We most often use hydrated silica, which is exactly the same stuff you find in the little packets in your vitamin bottles and shoe boxes. So that's the story of toothpaste. I'm gonna

go brush my teeth.
